title: (E)-2-{[1-(3,11-Dimethyl-4-methyl-ene-10-oxo-1-phenyl-4,5,10,11-tetra-hydro-1H-benzo[b]pyrazolo-[3,4-f][1,5]diazo-cin-5-yl)ethyl-idene]amino}-N-methyl-N-(3-methyl-1-phenyl-1H-pyrazol-5-yl)benzamide.
abstract: The central eight-membered ring of the title compound, C40H36N8O2, deviates from the ideal boat conformation because the bond between the exo-ethyl-ene group and the adjacent N atom is twisted by 60.0 (4)° due to steric hindrance. Its adjacent benzene and pyrazole rings are oriented almost perpendicular to each other, making a dihedral angle of 85.8 (3)°. In the crystal, the mol-ecules are linked by C(ar)-H⋯O hydrogen bonds, generating a three-dimensional network.
